• Greater chemical resistance than polycarbonate
• Can be autoclaved repeatedly—last longer than polycarbonate tubes under conditions of repeated autoclaving
• Can be used up to 50,000 x g in refrigerated or non-refrigerated centrifuges; 3139-0050 can be used up to 100,605 x g in the T29-8x50 rotor
• Come with polypropylene sealing caps with silicone gaskets for extra leak protection when spinning >10,000 x g or spinning hazardous materials
• Must be filled to 80% of total capacity when centrifuging
